hello -
EDITED:
is there any way to tell by looking at the apache environmental variables if a page forward came from an old(er) cached page?
in other words, say i had a webpage that contained the following link:
http://myDomain(dot)com/index.php?input=oldLink
and then i changed it to:
http://myDomain(dot)com/index.php?input=newLink
looking at /input.php, is there an apache variable somewhere that might tell me that the use of “oldLink” is coming from a cached website?
i should think that anybody who is coming to my server with 'oldLink" is using a cached page.
thank you very much.
